Equivalent Circuits for Cylindrical-Rotor, Reluctance, and Salient-Rotor Synchronous Machines

This paper presents a unified approach to the steady-state analysis of polyphase synchr-onous machines of three major types: cylindrical rotor, reluctance, and salient rotor. The major magnetic parameters of the machines are derived. Single-phaseequivalentcircuits are developed for each of the machine types. These equivalent circuits may be incorporated directly into the single-phase network representing a power system.
